WASHINGTON: Engineers in the US have developed TV displays based on a telescope design invented by Isaac Newton to reduce the display's electricity consumption.
The rear layer of a conventional liquid crystal display (LCD) used in televisions produces light (backlight), whose brightness is controlled by small liquid crystals that swing round like tiny shutters.
However, most of this backlight is wasted and never reaches the viewer.
Swapping the liquid crystals with microscopic mechanical mirrors arranged in a similar way to a telescope design invented by Isaac Newton can make much more efficient use of the backlight.
